PURPOSE:To decrease data transfer time by providing a protocol layer reporting the state of the number of idle reception buffers of each station and another protocol layer controlling an opposite station of data transfer and its control. CONSTITUTION:Stations A, B consist of application CPUs 5, 5' and communication control sections 6, 6' and they are connected through cables 7, 7', transceivers 8, 8' and a coaxial cable 9. The protocol layer reporting the state of the idle reception buffer number of the stations A, B and the other protocol layer controlling the opposite station of data transfer and its content are provided and a data request message is made unnecessary in a data transfer sequence where one data message is a prescribed amount or blow. |
